HENRY D. SMITH, OF EAST ST. LOUIS, ILLIITOIS.

SYSTEM FOR LUBBICATING INTERNAL-COMBUSTION ENGINES.

Application filed May 1,

To all whom it may concern: I

Be it known that I, HENRY 1). SMITH, a citizen of the United .States, residing at East St. Louis, in the county of St. Clair and State of Illinois, have invented certain new 'and useful Improvements in Systems for Lubricating Internal-Combustion Engines, of which the following is a specification; v Primarily this invention relates to means for supplying lubricating or heavy oil to the interiors of cylinders of an internal combustion engine and it consists in the novel features hereinafter described and claimed. Coincidently the invention serves as means for retaining and utilizing esca ing gases within the explosion chambers o I the engine and furthermore serves as means for subjecting the spark points of the'ignition devices to baths of heavy oil whereby carbon is prevented from accumulating upon the points.

The invention is intended to be applied to internal combustion engines such as are employed in the operation of motor vehicles and provides means for establishing a transportation system, extraordinary, for oil, from the crank case of the engine to the cylinders and applied to the inaccessible and more remote parts of the cylinders and pistons, effecting superior lubrication and economy by sealing, with heavy oil, the spaces around the peripheries of the piston mugs and preventing the escape of the elements of gasoline from the cylinders and its delivery to the crank casing whereby the explosive elements are retained where they may be immediately utilized by the next succeeding explosion within the cylinders.

Various types of oiling systemsare in use I in difierent types of motors but in common,

each has its reservoir from which oil is splashed or otherwise served to the moving parts, and it is notable that much vapor, containing gasoline, passes, under pressure, from the cylinders around the piston rings and thus gasoline finds its way and is delivered to the crank casing, where it cuts the oil and destroys its lubricating qualities. In the use of the present invention such destr uctive processes is prevented by sealing the spaces between the pistons and cylinder walls and confining the gases in the explosion chambers for use there.

A further object of the present invention and a breather nozzle lees. Serial No. $35,889,

is to provide means for moistening and oiling the points of the electric devices which furnish the sparks to set 01? the mixture in the cylinders, so as to prevent the accumula-' tion of carbon thereon and thereby inviting strong or hot sparks. This object is attained partly by serving heated-oil and partly by the presence of steam within the cylinders. The steam .is generated in the heater of the device by the separation of the water, usually present in small quantities in fuel oil, and its vaporization under the heating efl'ects of the hot oil.

In the accompanying drawin Figure 1 is a side elevation o apphed.

Figure 2 is a longitudinal sectional view of the same.

The other figures are detailed views of the features of the invention.

The device comprises a cup 1 adapted to be inserted in the mouth of the spout 2 of the crank casing 3 of the engine. A. fitting 4 is inserted in the upper end of the cup 5 is fitted in the upper end of the fitting. A concaved pan 6 of thin metal is interposed between the lower end of the fitting 4 and the cup and the said pan is provided with openings 7 located near its edge. The fitting 4 is provided at its side with a nipple 8 to which one end of a-hose section 9 1s connected. A wick 10 extends through the hose section 9 and one portion of the wick is diametricallyexpanded as at 11 and thesaid expanded portion rests in the concavity of the pan 6. The breather nozzle 5 is provided with a rotatable cap 12 having a slot 13 which may be brought into register with a similar slot in the nozzle. This arrangement forms one of the air sets of the device. By turning the cap 12 the volume of the air which passes through the breather nozzle may be regulated and when the slots are completely out of register with each other the flow of air is stopped and the breather is made air tight; The oil or vapor of the oil in the crank casing may pass through the spout 2, cup 1 and the openings 7 in the pan and is absorbed by the expanded end 11 of the wick and by capillary attraction is carried by the the wick through the hose section 9.

The heater of the device comprises a casting 15 of iron which is cored out and which is adapted to fit against the exhaust manithe device fold 16 of the engine. The heater casting is held in position upon the said manifold by a metal tape 17 The forward end of thecasting ispartially closed by a cap 18 which is turnably mounted upon the casting. The cap is provided with an opening 18 or openings, adapted to register with similar 0 enin 19 in the sides of the casting an by this means the quantity of the air which is drawn through. the casting is regulated This device is the second air set.

The cap 18 is held at a set or adjusted position by a set screw 20 which engages the casting and which passes through a slot 21 in the side of the cap. The posterior end portion of the casting 15 is offset as at 22 and the end of the wick 10 terminates in this ofiset portion. This ofi'set portion serves as a mixing chamber and may receive heated air. from the body of the heater casting and oil 'vapor from the wick and hose section 9. By adjusting the air sets the relative quantities of the heated air and the vapor may be regulated.

To more thoroughly mix and split the currents entering the heater and mixing chamber, a fan 23 is freely journaled in the ofiset and is rotated b the currents passing therethrough. A ose section 24 connects the offset 22 with the carbureter'25 and in turn the carburetor is connectedwith the engine intake manifold 26 in a usual manner. The fan acts to agitate the combined currents from the chest to and through the connected hose 24 and the carburetor, where the said combined currents are mixed with the liquid fuel in the carbureter and is passed through the .intake manifold into t e upper portions of the engine cylinders.

By closing the air sets the oil vapor, if required, may be drawn from the crank casing to the heater by the suction created within the parts connecting the heater with the breather of the crank casing, By adjusting the air sets, oil vapor may be carried to the heater. The pen economizes the oil as the expanded end of the wick lies over the openin in the pan and the oil is compelled to lter through the fibre of the wick to pass above the pan. At the heater the oil undergoes a physical and chemical change as it is converted by heat nected in the hose and adapted to be applied to the exhaust manifold of the engine, and means for inducting. atmospheric air into the heater.
